A tool, such as, a socket, that is adapted to remove a stripped or otherwise difficult to remove fastener. The socket includes a body having first and second ends, a first axial bore in the first end adapted to receive the stripped or cylindrical fastener head, and one or more cutting channels in the body between the first and second ends forming internal cutting edges adapted to engage the stripped or cylindrical fastener head. The one or more cutting apertures may have an elongated diamond-like shape and extend a portion of the way around the body and toward the second end.

A torque wrench, including: a head region with a receiving opening; a bending-resistant shaft region adjoins the head region; a support formed on the shaft region; and an actuating lever including an elastically bendable portion and a handle. The receiving opening receives a screwing instrument and defines an axis of rotation. The actuating lever, in resting position, is spaced apart from the in the circumferential direction to the axis of rotation. If a screwing instrument is inserted into the opening, the actuating lever transmits a torque. The wrench has an indicator region, which the exerted torque can be read as a result of the deflection of the actuating lever. When a reference force is reached, the bending portion comes into contact with the support. When a force is applied, the bending portion can be in the tightening direction and the torque can be read in the region.

An attachment tool includes an image capturing unit configured to capture an image of a random pattern provided on a comparison region of a part; and an identification result-outputting unit configured to output a part identification result obtained by comparing an image characteristic of the captured image of the random pattern with a previously stored image characteristic of a random pattern of a part.

A hand tool or wrench with a ratcheting mechanism. The wrench includes a number of components such as an abutting block and a pawl for use in a bistable ratchet operation. The wrench includes a ratchet mechanism that provides stable seating of the components, so that the mechanism is securely retained in a driving mode, as well as enabling a user to select a driving mechanism with ease so as to improve work efficiency.

A tensioning device for extending a threaded bolt by tensioning the threaded end section has a supporting tube surrounding the threaded end section, a cylinder arranged in continuation of the supporting tube and having at least one piston axially movable therein, an exchange socket which is screwable to the threaded end section and is configured such that it can be carried along axially by the piston, and a pin arranged in an axially movable manner in a longitudinal guide in the exchange socket. The pin end is axially supportable against that end of the threaded bolt that has the threaded end section. In order to assess the actually usable thread projection even in cases in which known tensioning devices provide imprecise results, the pin is formed in a radially widened manner at its pin end compared with the pin cross section.

An apparatus includes a tool assembly. The tool assembly includes a tool device configured to securely receive, at least in part, a nut. An angled elbow assembly is configured to be positioned proximate to, and securely integrally extended from, the tool device. A linearly-extended elongated shaft portion is configured to have a first end portion and a second end portion spaced apart from the first end portion. A step-pad assembly includes a first side portion facing the second end portion of the linearly-extended elongated shaft portion. A second side portion is configured to extend from the first side portion. The linearly-extended elongated shaft portion does not extend through the step-pad assembly and out from the second side portion of the step-pad assembly.

The present invention provides a wrench comprising a handle, having a cylindrical inner surface as a first surface; a torque output member, arranged within the first surface of the handle, the torque output member having a cylindrical outer surface as a second surface; one or more wedging member(s), arranged between the first surface and the second surface; varied distance being between the first surface and the second surface, so that the wedge members can prevent the rotation of the first surface relative to the second surface in a predetermined direction. The wrench according to the present invention adopts wedge member to prevent the rotation of the handle relative to the torque output member. When the handle idles relative to the torque output member, only the wedge member will leave the stop position and no sound will be made. Such a wrench is a quiet wrench. Adopting such a configuration not only can reduce wearing of the wrench, extend the service life of the wrench, and improve the user's experience. Providing pre-tightening force can effectively reduce the interval and make the operation smoother.

A detachable and torque-adjustable cross wrench includes a primary bar and a torque-setting secondary bar, and an end of the primary bar is a socket insertion end and the other end of the primary bar is installed with an assistant turning handle provided for pivoting. A penetrating hole formed at a thickening middle section is provided for connecting the torque-setting secondary bar to form a cross wrench. The torque-setting secondary bar includes a plugging inner rod with a spacer ring slot, a force applying outer rod containing a torque-setting module, a handheld turning handle, an elastic pushing member, a torque-adjusting screw cap and a retaining ring. The torque-adjusting screw cap is provided for rotating and adjusting the torque-setting module to a predetermined torque value, so as to achieve an expected torque-setting.

A combination fire hydrant ratcheting wrench and hook spanner is disclosed that incorporates a wrench body having a number of interchangeable ratchet sockets, hook spanners, spanner indentations and an extendable handle. Such that the wrench sockets may loosen or tighten a pentagonal shaped implement such as a hydrant cap, cover, or valve. Utilizing the hook spanners or spanner indentations the wrench may remove or replace fittings such as reducers and increasers, further the wrench may loosen when connected on a wrench top surface and tighten when connected on a wrench bottom surface.
